9 Claims.

This invention relates to new and useful improvements in iiask cars employed in plants for y manufacturing cast iron pipes and the like.

These cars are designed to carry four flasks each and are employed for transporting 'the flasks from one point to another in the plant. It is very necessary that these flasks be handled as gently as possible because of the long slender cores used in making the castings. Any slight jarring of the flask may cause sand to fall off the core bar and the result will be a spoiled casting and a damaged core bar.

Among the several objects of my invention are l5 to provide a car of skeleton construction whereby the sand and the gates are able to fall through the car at the shake out point; to provide such a car with shields or deflectors which will direct any sand, which may drop from the flasks` while in transit, away from the rails; to provide cushioning means for supporting the flasks on the car; to provide the car with hooks at opposite ends for use in lifting the car and transferring the same from one track to another, and to provide a car which is of simple and light construction and therefore requires very little effort to be pushed along the track.

With these and other objects in view which will more fully appear, the nature of the invention will be more clearly understood by following the description, the appended claims, and the several views illustrated in the accompanying drawings.

In the drawings:

Figure l is a top plan Viewy of a flask car constructed in accordance with my invention,

Figure 2 is a horizontal sectional view thereof,

Figure 3 is a side elevation of the car,

Figure 4 is an end elevation thereof,

Figure 5 is a vertical cross section taken on '40 the line 5-5 of Figure l, and

Figure 6 is a perspective View showing in separated relation one of the transverse beams and portions of the longitudinal beams.

Like reference numerals vdesignate corresponding parts throughout the several figures of the drawings.

Referring to the accompanying drawings7 my invention embodies a car body A and supporting wheels B adapted to be moved along rails 5, 5.

The body A is of skeleton form and includes spaced longitudinal beams 6, 6 and spaced transverse beams 'I, l.

The longitudinal beams 6 which are disposed directly above the rails 5, are each formed of 5 sheet metal and are of inverted U-shape in cross section to include flat vertical edge portions B, S and a connecting hood portion 9. Angle iron braces ID, IU are rigidly attached by welding or other means to the inner faces of the vertical edge portions 8, the horizontal flanges II, II of the braces projecting towards each other in the horizontal plane containing the lower edges of the beams. The ends of each beam 6 are closed by plates I2, I2 and rigidly attached to these plates arey hooks I 3, I3 for use in hoisting and transferring the car from one track to another.

The transverse beams I project beyond the longitudinal beams 6 and are each of I-beam construction. The lower portions thereof are formed with upwardly projecting recesses lli, lt to receive snugly the hood portions 9, 9 of the longitudinal beams 6, the edges of the recesses being welded to said hoods. Rigidly secured to the head of each transverse beam are spaced chocks I5, l 5 and secured to and extending along the upper faces of the transverse beams are cushioning pads IS of rubber or other material.l

Intermediate cross braces Il, Il which are preferably of angle iron construction, are located intermediate the transverse beams l, l and .are rigidly secured by welding or other means to the lower faces of the horizontal flanges I i of the longitudinal beams. End cross braces i8, iii which are preferably of angle iron construction, are located at points between the ends of the longitudinal beams and the transverse beams and are rigidly connected to the lower faces of the horizontal flanges I I of the longitudinal beams by welding or other means.

Spaced pairs of bearings I9, I9 which are disposed directly under the cross beams l, 'l are bolted to the lower faces of the outer horizontal flanges II of the longitudinal beams, and journaled in these bearings are transverse axles 2li, 20 to which are fixed the wheels B. The Wheels B are located directly below the longitudinal beams 6 and have their upper portions projecting into said beams between the flanges' I I, II thereof.

In order to prevent the longitudinal beams E from becoming depressed by a load of flasks, I have provided each beam with vertical braces ZI, 2I which are located in register with the transverse beams I and the bearings I9. These braces aref seated upon the upper faces of the outer anges II of the longitudinal beams and their upper edges contact the inner faces of the beams 6.

From the foregoing, it will be observed that four flasks may be positioned on the transverse beams l, 1; that the chocks l5 serve to act as guides in placing flasks on the car and maintain the flasks in parallelism on the car; that the cushioning pads function to reduce the shock to the flasks when being placed on the cars and vibration of the flasks when the car is moving, thereby lessening the tendency of sand to fall off the core bars and reducing the loss of sand from the flasks to a minimum; that the wheels and the rails are protected from falling sand by means of the inverted U-shaped longitudinal beams; that the sand and gates are able to fall through the skeleton car at the shake out point, and that the car may be easily lifted and transferred from one track to another.

It is of course to be understood that the details of structure and arrangement of parts may be variously changed and modified without departing from the spirit and scope of my invention.
